3 Description

The TPS3762-Q1 is a 65V input voltage supervisor

with 4μA IDD, 0.9% accuracy, fast detection time

(5μs), and a Built-In Self-Test feature. This device can

be connected directly to 12V / 24V automotive battery

systems for continuous monitoring of overvoltage

(OV) and undervoltage (UV) conditions; with the

internal resistor divider, the TPS3762-Q1 offers the

smallest total solution size. Wide hysteresis voltage

options are available to ignore large voltage transients

and prevent false reset signals.

The separate VDD and SENSE pins allow

redundancy sought by high-reliability systems and

SENSE can monitor higher and lower voltages than

VDD. Optional use of external resistors are supported

by the high impedance input of the SENSE pin. CTS

and CTR pins allow delay adjustability on the falling

and rising edges of the RESET signal. The CTS

functions as a debouncer by ignoring voltage glitches

on the monitored voltage rails.

The TPS3762-Q1 is available in a 2.9mm × 1.6mm

SOT23 8-pin package.
